Do I see oil lines running up the A-Pillars? Not sure I've seen that before. Is there a special reason for that type of routing?
They're not oil lines, they are vent lines - vent from the engine to the oil tank, and vent from the oil tank to the 'catch' can in the back (which I know is way too big but the guy that built it years ago made it really nice...so we just left it).
I know lots of people vent the engine to a catch can close to the engine - that's how Huey is too. But with a high compression race engine, we found it was better to vent to the oil tank (like they are designed to do), but since the tank is up front....
Its actually pretty common on bigger/high compression engines from what I've seen. I don't really like it...but when the guy that's been doing this for practically longer than I've been alive says it needs to be this way...and the engine runs flawless...I don't argue!
